Sanding and Fairing and Building the Edges

Greg and I havent forgotten about you, this blog, or our project. Its just that we havent recently hit any milestones worth blogging about. As I mentioned in some of my recent postings, the part were on now is very long and tedious... not much worthy of a blog entry. Despite my lack of posting though, we have made significant progress, and its very close to the rate that I expected. This is largely due to Gregs work.

My family and I went to California for vacation recently, which prevented me from assisting Greg for two weeks straight. In all honesty, I suspected that very little would be done during my absence. (This is partially because much of what weve done to date is highly expedited by having two people working, and partially because I realize that I help keep Greg motivated.) But when I got back home, I was pleasantly surprised to find that Greg had made significant progress during my absence. While I was gone, Greg enlisted the assistance of our mutual friend Dan. Dan, thanks for your help while I was gone. I appreciate it, and I know Greg appreciates it.

As you can see in the first photo, Greg and Dan made great progress in filling the bottom of the boat. Its very close to being finished.

Greg also made a lot of progress in rebuilding the hard edges of the boat. Remember, this boat is designed to have a planing hull, so a perfectly flat bottom and very hard chines are essential in order to have this boat perform as expected at planing speeds.

In the picture to the right, you will see how we made the chines with relatively little work. Greg screwed thick sheets of plastic to the hull, as shown in this picture. This gave us (when I say "us," Im including Dan, because he was part of this particular process; he also provided us with the plastic.) a fairly straight, and very sturdy platform with which to work. We wedged epoxy thickened with wood flour and fiberglass particles into the space between the plasic, going slightly higher than the bottom of the hull. This way, we were sanding down, instead of requiring a second fill coat.

In this picture, you will notice the applied thickened epoxy. After the epoxy dries, we remove the sheets of plastic, and voila, a sturdy chine, ready for sanding.









This shot will give you a basic picture of what the chines look like after the epoxy sets and the plastic is removed. What youre looking at is the starboard side. You will notice that the chines are not built up throughout the whole starboard side. This is because of the limited plastic available. It will require a second session to finish the side. You will also notice that we (again, "we" includes Dan) have been sanding and fairing along the entire bottom of the hull.

This final picture is taken from the bow, starboard corner. You will notice that Greg has also filled the front transom area, and the front bottom area, to compensate for the three-to-six layers of fiberglass. You will also notice the fair amount of fairing done on the bottom, and the hard chine. Like Ive said, its not that we havent been working, and its not that weve forgotten about you. Its mainly that were at a relatively tedious section of the project, and theres not a lot to report. After all, how many times can I say "Yep, were still sanding" and keep you all interested?

Until next time...

Oh yeah, you may have noticed that the boat has several different colors of filler. This is because Greg is utilizing a combination of whats cheapest and what works best for sanding and fairing in a given area of the boat.

sanding seats and rowlocks

more and more sanding.  the interior was far easier to sand as there was no fiberglass cloth insided. 

I found some excellent #2 1X10 pine that works great for the seats.  My local lumberyard has wide planks of this #2 that is way better than anything of any grade seen at the big box stores.  I took the boat over to the local lake and fiddled with seat placement and rowlock placement using four C clamps as temporary Thole pins.  As indicated on the plans I went 1.5" aft for the seat and the rowlocks are 13.5" aft of the back edge.  The aft seat appears to be a bit wide as if it were 8.5" would act as a foot brace.  I wont tack this in place until I am sure, but at least I know where the rowing seat is going and will install the cleats that hold it in place tomorrow. 

I did find it interesting that no matter how much I thought I had got all the rough spots with sandpaper, there were a few I missed that became apparent once I got it out in the middle of the lake. 

More interesting to anyone reading this is that this boat rows very well!  It tracks straight as an arrow and gets up to hull speed easily even with the 6 1/2 oars I used rather than the 7 recommended by the designer.  I hope to get some paint on it this week and some photos soon. 

The finish work takes much longer than actually building the hull.

A Brief Diversion

You may have noticed a lack of recent posts about our boat project, and if you think its because we havent done anything lately, youre right. You see, its almost time for our annual boyz trip pilgrimage. Every year over Memorial Day, Greg, two of our friends from high school and I go on an extended trip. The trips have varied tremendously over the years... sometimes we do long, self-contained downriver canoe trips, sometimes we do whitewater kayaking, occasionally more than the "core four" of us will go. Our trips have varied from three days to a week, and we have hit too many rivers to count. We started out taking these trips over Labor Day weekend, but changed to Memorial Day a few years back when we figured out that the water levels are generally higher this time of year.

This year, we will be travelling to North-Central Wisconsin and doing a self-contained island-hopping lake canoe trip, utilizing the canoes we built a couple of years ago. To add to the adventure, Greg and I are temporarily converting our individual canoes into a catamaran sailing vessle. Were going to a brand new area, doing a variation on our trip that we havent really done before, and trying a new feat of engineering. This should explain the lack of progress on the main project. Weve been planning the trip, and working on the rig that will convert our paddle-powered canoes into a wind-powered catamaran.

If you’re interested in some of the history and stories from our various trips, here are a few links for you to check out…

All of the seams are now sanded and rounded. Weve got a procedural question in to the gurus about taping the corners. Apparently, some people plane the hull where the seams are, and the result is a lot less sanding. Well let you know when we find out.

Sanding Sanding Sanding

It took about 3 hours to sand the drips, and runs on the skiff to a surface that is almost fair.  I found a couple of spots where the glass had bubbled up and not adhered to the hull .  These places have been faired with WEST System fairing putty and will be sanded down tomorrow.  No photos as this is just grunt work.  Pretty boring and my least favorite part of boatbuilding. 

For the skeg, I am laminating up a 3/4 X 3 1/2  piece from 1/2" marine ply with a lamination of leftover Okoume.  All the other stuff in the garage is the wrong dimension or warped.  Skeg needs to be straight.  pretty easy to clamp along the top of a sawhorse, will use release film so it doesnt stick.  This should work.   

If there is a moral here, it would be to apply thin coats of epoxy and dont get greedy.  It is going to take 3 coats no matter what.  If you put too much on, it will just run and need to be cleaned up. 

Hope to get the third coat on tomorrow.  Looking like this really will be a first class finish.  I am looking at painting with the Ben Moore oil base if I can find it.  High gloss.

No More Sanding

Thats not exactly true, but it feels good so say it and mean it... at least in this context. Yes folks, Greg finally said "good enough" and decided it was time to paint. In a desire to support this decision (and get a coat of paint on the boat before he changed his mind), we did a rare Saturday session. Between the final round of sanding (a quick but thorough sanding of both transoms and sides with 220-grit sandpaper), prepping the surface, mixing the paint, and the roll and tip process, we put in roughly four hours.

We had the little Ozzlet there to help us out. Shes a great little photographer, and she also helped us prep the surface, paint a little of the hull (rolling, not tipping) and she watched Gregs girls.

On Tuesday (our regularly scheduled boatbuilding day), we will do some light sanding as needed and apply a second coat of paint. Were planning to flip the boat sometime between late November and mid-December.

I know well be doing some touch-up sanding between coats, and I understand that well be doing another round of sanding and fairing when we build the deck and cabin, but it shouldnt be quite as long and arduous as the hull. I cant describe how gratifying it is to be out of sanding and fairing hell.

I have several more pictures here...

new coat of paint

I could not stand the look of the latex house paint.  It just did not have the gloss that makes a first class job stand out, and it was very subject to abrasion.  So, today I stripped off the latex and repainted with Hi-Gloss White enamel by Benjamin Moore.  Using a roller, and tipping of with a nice brush yielded an excellent finish that I am sure will give this boat the attention it deserves.  Some wet sanding with 600 grit should yield a first class finish. 

One more coat to go with the varnish, and finishing the interior with a coat of the Kirbys battleship grey should give me a finish that is easy to sweep out or wash off.  Also need to finish sealing the seats.
